When listeners search for the referent of a speaker's expression, they experience interference from privileged knowledge, knowledge outside of their "common ground" with the speaker. Evidence is presented that this interference reflects limitations in lexical processing. In three experiments, listeners' eye movements were monitored as they…

Language is an intrinsically open-ended system. This fact has led to the widely shared assumption that readers and listeners do not predict upcoming words, at least not in a way that goes beyond simple priming between words. Recent evidence, however, suggests that readers and listeners do anticipate upcoming words "on the fly" as a text…

Real-time estimation of what we will do next is a crucial prerequisite of purposive behavior. During the planning of goal-oriented actions, for instance, the temporal and causal organization of upcoming subsequent moves needs to be predicted based on our knowledge of events. A forward computation of sequential structure is also essential for…

Research concerning the spatial dimension "fit" ("tight" versus "loose") has been based on a tacit but untested assumption that the dimension "fit" is symmetrical, with tight- and loose-fitting relations highlighting the dimension "fit" with equal force. We propose a reformulation, documenting that adult speakers of English (Experiment 1) and…

Four dual-task experiments examined visuospatial, articulatory, and central executive working memory involvement during the development and application of spatial mental models. In Experiments 1 and 2 participants read route and survey spatial descriptions while undertaking one of four secondary tasks targeting working memory components.…

Two auditory ERP studies examined the role of animacy in sentence comprehension in Mandarin Chinese by comparing active and passive sentences in simple verb-final (Experiment 1) and relative clause constructions (Experiment 2). In addition to the voice manipulation (which modulated the assignment of actor and undergoer roles to the arguments),…

The role of the right hemisphere for language processing and successful therapeutic interventions in aphasic patients is a matter of debate. This study explored brain activation in right-hemispheric areas and left-hemispheric perilesional areas in response to language tasks in chronic non-fluent aphasic patients before and after constraint-induced…

Filled-pause disfluencies such as "um" and "er" affect listeners' comprehension, possibly mediated by attentional mechanisms (J. E. Fox Tree, 2001). However, there is little direct evidence that hesitations affect attention. The current study used an acoustic manipulation of continuous speech to induce event-related potential components associated…

The objective of this study was to investigate the effects of working memory capacity, access to subordinate meanings of L1 homonyms and degree of cross-language activation on the access to subordinate meanings of L2 homonyms. In Experiment 1, Spanish-English bilinguals completed a word recognition task which assessed how quickly and accurately…

This dissertation reports the results of within-English structural priming experiments in language production which investigated the syntactic representations of English syntactic structures in three different bilingual groups: Japanese-English, Korean-English, and Mandarin Chinese-English bilinguals. Specifically, my dissertation research…

Universities are increasingly looking into self-service systems with intelligent digital agents to supplement or replace labor-intensive services, such as academic counseling. The Open University of Hong Kong has developed an intelligent online system that instantly responds to enquiries about career development, learning modes, program/course…

This study investigated first language (L1) influence on the acquisition of second language (L2) collocations using a framework based on Kroll and Stewart (1994) and Jiang (2000), by comparing the performance on a phrase-acceptability judgment task among native speakers of English, Japanese English as a second language (ESL) users, and Japanese…

We present a neurocomputational model with self-organizing maps that accounts for the emergence of taxonomic responding and fast mapping in early word learning, as well as a rapid increase in the rate of acquisition of words observed in late infancy. The quality and efficiency of generalization of word-object associations is directly related to…

The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…

This article presents the concept development, research programming, and learning design of a lexical processing web application, Virtual Vocabulary, which was developed using theories in both cognitive psychology and second language acquisition (SLA). It is being tested with first-year students of German at the University of Victoria in Canada,…
